If I try site.co.uk/categories everything's fine but if I try site.co.uk/categories/7 to pass some data the page doesn't load the CSS file (even though the source code looks ok) and the images, but does receive the number.

Can anyone see where I'm going wrong?

I Should add that if I use site.co.uk/index.php?p=categories&cat_id=7 everything works as it's meant to.
